BOILER CLEANER.

Application filed April 23, 1921. Serial No. 463,774.

An object of the invention is to provide in a boiler cleaner having an automatic 1 means for controlling the flow of cleaning fluid to the blower unit, of means for indicating when the steam is flowing through the blower unit.

Another object is the provision in a boiler 11 cleaner, of this class of an alarm so positioned as to be operative while the cleaning fluid is being delivered to theblower unit.

I Other objects will appear hereinafter.

a The invention consists of the combinations and arrangements of scribed. and claimed.

The invention will be best understood by reference to the accompanying drawing which forms a part of this specification and which illustrates the'invention. Fi ure 1 is a side elevation ofmy device app ied to a boiler cleaner showing a vertical sectional view thereof, and Figure 2 is a detail view I along 2-2 of Figure. 1.

In a boiler cleaner of this class a blower unit which comprises a'pipe having a series of perforations therein for the discharge of cleaning fluid therefrom is inserted into the interior of the boiler setting in such aposition that thesteam or'cleaningfluid discharging from'the openingsformed in the blower unit will serve to remove the soot and ash "from the boiler tubes, the blower unit' being rotatable so as to direct the jets of steam over a maximum area.

- To aflord the necessary space for assembling the rotating mechanism there is pro- 4, and the upper end thereof extending as longitudinally and being likewise opened.

One end of the blower unit 6 is slidably posiparts hereinafter de-,

vlded a goose neck 3 open at its lower end bracket being secured by a bolt 13 to a" shoulder 14 formed on the lower portion of the goose neck, said bracket serving to retain more rigidly the unit 6 as will be readily understood.

Rigidly mounted upon the unit 6 is a gear wheel 15, a set screw 16 being projected through the hub thereof for engaging the unit 6. Positioned upon the unit 6, loosely,

is an annular member 17 which engages at one side thereof, the ball bearings 20' positioned in pockets formed'in the member 18 this latter member being also loosely positioned upon the member 6, said ball bearings 20 also engaging an annular member 19 loosely positioned upon the unit 6. Thus the diameter of said ball bearings being greater than the width of the member 18, the ball bearings project "from opposite-facesof the member 18 so asto engage the rings or annular members 417 and 19. A collar 21 is positioned on the member 6 and engages the bracket 12 The purposeyof these annular members is to. relieve friction and facilitate turning of the member 6. When the steam is turned into the unit it has a tendency to thrust the same forwardly into the settings of the boiler. By interposing the ball bearingarrangement the hub of the wheel engages a rotatable member and the turning of the unit '6 becomes much easier than if the hub engaged either the I I bracket 12 or the collar 21."

An interrupted band or rim 22 is securely fastened to the wheel 15 bya bolt. 23 so as to partially surround the blower unit 6. p

Positioned in the portion 4 of the goose neck 'isa valve seat forming member 24 which comprises an annular ring radiating from which are a number of legs or arms 24 so as to constitute a spider, said arms convergingto and being formed preferably integral with a hub through which a valve stem 25 projects.- Said stem pro ects exteriorly of the goose neck, secured to the interior end of the stem 25 is a nut 26 which threads into a socket formed in a valve or plug 27. Said member 27 is normally retained in engagement with the valve seat 24 by means of a spiral spring 28 one end of whichenga-ges said member ,2 7 other endof which engages the delivery pipe 30 which is. threaded into a gland 29,

said pipe 30 beingconnected to any suitable source of fluid supply.

and the V v Mounted upon the goose neck is a pair of spaced lugs 31 and 31. Pivotally mounted upon these lugs between the same is a lever 32. The construction is such that upon rotating the wheel 15 in one direction the lever 32 is engaged bythe member'22 and pressed downwardly so as to open the valve in the lower portion of the goose neck and thereby admit steam to the blower unit.

,Upon rotating the wheel in the opposite direction the end of the lever 22 engages behind the member 22 and prevents further rotation of the unit in that direction. The wheel 15 may be caused to rotate by any suitable means.

With a boiler cleaner such as described should the rotation of the unit 6 stop at any time when the lever 32 is pressed downwardly the steam which would be delivered to the blower unit would continue to issue and strike the blower tubes in one set place. To eliminate the possibility of such a'thing happening I have provided a steam whistle 33 which is mounted in communication with the goose neck above the valve 29. It is apparent so long as steam is delivering to the unit 6 the whistle 33 will serve to sound an alarm thereby warning the operator that the lever 32 is still depressed by the member 22.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. In combination with a boiler cleaner comprising a'" rotatable blower unit, means for rotating said unit and means automatically operated by the rotation of said unit for controlling the-delivery of fluid to said unit and alarm means for forcibly impressing upon the operator the fact that the fluid is being delivered to said unit.

2. The combination with a boiler cleaner comprising a blower unit, of means for controlling the delivery of cleaning fluid to said unit and alarm means for forcibly impressing'upon the operator the fact that the fluid is being delivered to said unit.

3. In combination with a boiler cleaner comprising a rotatable unit, a head in which said unit is mounted for rotation, a supply of steam leading to saidhead, a valve for controlling the supply of steam to said head and means located in said head for forcibly impressing upon the operator the fact-that the cleaning fluid is being delivered to said unit.

4. In combination with a boiler cleaner comprising a rotatable blower unit, a flui supply having a control valve, means for rotating said unit, a'control member rotatably. mounted upon said unit, a lever having an end engaging the control member and operated thereby, and a connection between the other end of the lever and the valve, whereby the valve is automatically controlled by the rotation of said unit, and an alarm means for forcibly impressing upon the operator the fact that the valve is unseated thereby delivering cleaning fluid to the unit.

5. A boiler cleaner comprising a blower unit, a supply pipe therefor, an audible alarm in the supply pipe for forcibly impressing upon the operator the fact that the fluid is being delivered to the unit.

6; A boiler cleaner comprising a blower unit, a supply pipe therefor, and an alarm in the supply pipe for positively bringing to the attention of the operator the fact that cleaning fluid is being delivered to theunit.

' 7. The combination with a boiler cleaner comprising a rotatable blower unit, of-

a fluid supply having a control valve, a valve stem, means rotatable with the blower unit and adapted to actuate the valve stem for unseating the valve to supply cleaning fluid to the blower unit, and alarm means for automatically forcibly impress,

ing upon the operator the fact that the said rotatable means is actuatingthe valve stem to supply cleaning fluid to said blower unit.

8. A boiler cleaner adapted to discharge cleaning fluid adjacent parts of a boiler to be cleaned comprising a blower element, a pipe for conducting a cleaning fluid from a source of supply to said blower element, a

valve controlling the supply of cleaning fluid from said pipe to said element, means controlled by a movement of the blower element vfor automatically unseating the valve, and an alarm controlled by the pas sage of cleaning fluid to the blower element for forcibly advising the operator when said means is unseating the valve with consequent flow of cleaning fluid to the blower element, said alarm thus being adapted to assistthe operator in manipulating the boiler clean-er to prevent injury to the parts of the boiler lying in the path of the cleaning fluid being discharged and to prevent wasting of the cleaning fluid.

In testimony whereof, I have hereunto signed the foregoing specification at Detroit,

Wayne County, Michigan, this 15th day of d April, 1921.
